For security reasons if you incorrectly enter your PIN multiple times, your SmartCard will be temporarily suspended and will not work.
To unblock your SmartCard, you must call the Customer Service Centre on 1800 828 232 (freecall). The block will be removed within minutes and your SmartCard will be ready to use again. The block is removed automatically at midnight, so if you are unable to contact the Customer Service Centre, your SmartCard should work again the next day.
